Toilet buoy unit to control water flow

ABSTRACT

Toilet buoy unit to control water flow is a device to control water flow to let only small amount of water draining into toilet to flush human liquid waste. A flash light bulb is provided to tell us small amount of water being drained. People defecate once a day and urinate several times a day. If we use toilet buoy unit to guide us to drain small amount of water to flush liquid human waste we can save a large amount of water to relieve the shortage of water supply in big cities in the United Status.

THE BACKGROUND OF THE INVENTION

It requires only small amount of water to flush urine in toilet. Theexisting toilet flushing system flushes same large amount of water toflush urine as it does to flush feces. We urinate several times a dayand only defecated once a day. We waste a large amount of water to flushurine daily. If we use a smaller amount of water to flush urine we cansave a large amount of water to relieve the shortage of water supply inbig citied in the United States.

THE BRIEF DESCRIPTION OF THE INVENTION

The present invented toilet buoy unit to control water flow is a simpledevice to guide us to use small amount of water to flush urine. Itprovides a flash light bulb. When the toilet push-handlebar is pusheddownward to a certain level to drain certain small amount of water theflash light bulb is turn on. After small amount of water is drained fortwo to three seconds to flush urine user releases push-handlebar to shutoff water. If we push push-handlebar downward too much the flash lightbulb will turn off to tell us large amount of water is flushing and wehave to release push handlebar a little bit to let flash light bulblighted again to flush small amount of water.

When toilet flushing system is in closure status numeral54 of FIG. 3 is the distance from toilet water level 20 to the fronthook-ring 44 of toilet flapper tank ball 43. The first step to installthe toilet buoy unit to control water flow 10 is to let water fill uptoilet water tank. The second step is to measure the distance 54 fromfront hook-ring 44 to water level 20. The third step is to adjust thelength of lower chain 40 to make the distance from mark line 48 ofbuoyant cup 18 to inferior hook 42 of lower chain 40 equal to thedistance 54. The fourth step is to hook up front hook-ring 44 withinferior hook 42 of lower chain 40. The last step is to adjust thelength of upper chain 11 to make upper chain 11 near a straight lineafter upper hook 12 of upper chain 11 hooking up hole 52 of toilet lever50. The complete installation of toilet buoy unit 10 is illustrated inFIG. 3. When user pushes downward handlebar 51 to lift conductive metalring 32 upward approximate one and a half to two inches high to contactthe electric brush 28 to turn on flash light bulb 26 the front hook-ring44 of toilet flapper tank ball 43 is elevated approximate one and a halfto two inches to open the opening 55 of toilet water tank drainpipe 56to drain small amount of water to flush liquid human waste asillustrated in FIG. 5. If user pushes handlebar 51 further downward tolift the conducting metal ring 32 higher than electric brush 28 flashlight bulb will turn off to tell us large amount of water being drainingthrough opening 55 of toilet water tank drainpipe 56 to flush solidhuman waste as illustrated in FIG. 6.
